Part 1 of a few short videos of tufts applied to the Sonex wing to show airflow around the aileron and flap hinge lines. With the flaps deployed full the tufts show some airflow burble over the flaps, but the airflow off the wing (and over the hinge gap) looks fairly smooth. The joint where the aileron meets the flap shows some turbulence, probably due to air leakage from the bottom side.
